It is a line segment.
a fixed pulley is a pulley attached to a support.
They are points whose positions do not change under transformations.
I believe that is the definition of a straight line.
An axis.
FIxed reference points refers to a coordinate system or set of axes within which measure the position, orientation and other properties of an object in the drawing.
There do not appear to be ANY "fixed points" in the Universe. Everything is in motion, and there is no "preferred" frame of reference.
It is because all measurements are taken from that point: it is the fixed point of reference.
The fixed points of a function f(x) are the points where f(x)= x.
What is the fixed reference point in the photos?
Without a fixed Point of Reference, there is nothing to be relative to.
If the reference points are not correct, the location of any coordinate will be incorrect.
Axis
Reference points are used in order to easily access information that is in a larger collection of data.
If the row is variable but the column is fixed then it is a mixed reference. $A2 is a mixed reference. The row and column can be variable, in which case it is a relative reference.

If you have 2 then you are right. The freezing point of water and the boiling point of water are the 2 fixed points.
the set of points equidistant from a fixed point
